316 Mr. A. L. Butler on the 



Khartoum, along the White Nile to Duern (and probably 

 further), on the Blue Nile, and in Kordofan, frequenting the 

 cultivated lands in large flocks. Nowhere have I seen it in 

 such numbers as at the wells of Bara, in Kordofan. There, 

 at the end of April 1903, it had collected in tens of thousands, 

 in company with lesser, but great, numbers of Uroloncha 

 cantans. Every thorn " zariba " round the cultivated plots 

 was perfectly yellow with them. 



At Khartoum it is abundant in the summer and autumn, 

 but little in evidence during the cold months. 



The Rock-Sparrow, Petronia pyrgita (Heugl.), I have 

 never seen, though I have kept a sharp look-out for it ; I 

 think that it must be either very local or very scarce.

I have come across the White-rumped Serin-Finch almost 

 everywhere I have travelled — from the Setit to Western 

 Kordofan. It is fairly common along both the Niles, 

 associating in flocks. It is easily recognised among other 

 small Finches by its white rump. 



About September and October it is often seen in pairs 

 in the gardens at Khartoum, apparently breeding at that 

 season.

The beautiful little Indigo Finch is common and generally 

 distributed. It is a very famil'ar species, frequenting 

 villages and the compounds of houses in the towns, and 

 occasionally entering verandahs to drink from the large 

 earthenware filters. I have seen it in full plumage in 

 every month from August to March, but at all times of the 

 year birds in the blue plumage are greatly outnumbered by 

 the brown females and immature males. 



It is common in the town of Khartoum.
